IMPORTANT: Read entire instructions before starting the  
installation.  
II. SET DIP SWITCHES  
There are 4 small switches on the back of the circuit board  
which must be configured by the installer. The ON position  
is indicated by small letters on the switch. Ignore the num-  
bers (1-4) on the switch. The switch designation (A-D) is printed  
on a sticker next to the switch. To change a switch position,  
use the corner of a small screwdriver to slide the switch  
ON or OFF. Set the DIP switches before installing the  
thermostat.  
SAFETY CONSIDERATIONS  
Read and follow manufacturer instructions carefully. Follow  
all local electrical codes during installation. All wiring must  
conform to local and national electrical codes. Improper wir-  
ing or installation may damage thermostat.  
Recognize safety information. This is the safety alert symbol  
.
When the safety alert symbol is present on equipment  
or in the instruction manual, be alert to the potential for per-  
sonal injury.  
A. Air Conditioner or Heat Pump Selection (Switch A)  
Use switch A to select between air conditioning and heat pump  
applications. A heat pump application uses a reversing valve.  
Set switch A to OFF for air conditioning applications (no re-  
versing valve). Set switch A to ON for heat pump applica-  
tions (O is used to energize the reversing valve). The factory  
setting is OFF.  
Understand the signal words DANGER, WARNING, and CAU-  
TION. These words are used with the safety alert symbol.  
DANGER identifies the most serious hazards which will re-  
sult in severe personal injury or death. WARNING signifies  
a hazard which could result in personal injury or death. CAU-  
TION is used to identify unsafe practices which would result  
in minor personal injury or property damage.  
B. Compressor Stage Selection (Switch B)  
Switch B is used to select between a single-stage and a 2-stage  
compressor. Set switch B to OFF for a single-stage compres-  
sor. Set switch B to ON for a 2-stage compressor. The factory  
setting is OFF.  
GENERAL  
Bryant’s 7-day, commercial, programmable thermostats are  
wall-mounted, low-voltage thermostats which maintain room  
temperature by controlling the operation of an HVAC (heat-  
ing, cooling and ventilation) system. Separate heating and  
cooling set points and auto-changeover capability allow occu-  
pied and unoccupied programming for energy savings.  
C. Outdoor Air or Remote Room Sensor (Switch C)  
Switch C is used to configure the thermostat to work with  
either a outdoor air sensor or a remote room sensor. The sen-  
sor for the application must be connected to terminals S1 and  
S2 of the thermostat. Set switch C to OFF for a outdoor air  
sensor. Set switch C to ON for a remote room sensor. The fac-  
tory setting is OFF.  
All thermostats allow up to 4 time/temperature settings to  
be programmed per 24-hr period. Each thermostat stores pro-  
grams for 7 independent days. Batteries are not required. Dur-  
ing power interruption the internal memory stores comfort  
schedules for an unlimited time while the clock continues to  
run for at least 72 hours.  
D. Averaging of Sensors (Switch D)  
Switch D is used if a remote room sensor is being used (switch C  
set to ON). The remote room sensor reading can be averaged  
with the sensor reading of the thermostat. Set switch D to  
OFF if averaging is not required. To average the readings of  
the thermostat and remote room sensors, set switch D to ON.  
The factory setting is OFF.  
The thermostat can be configured to accept several different  
equipment configurations, from single-stage heating and cool-  
ing to 3 stages of heating and 2 stages of cooling. The ther-  
mostat comes factory configured for 1 stage of cooling and  
1
stage of heating.

11. Turn on power to unit. The thermostat will receive power  
from the unit.  
E. Anticipator Adjustment Selection  
On power up the thermostat display shows the selected setup  
mode (AC - single-stage air-conditioner, HP - single-stage heat  
pump, A2 - 2-stage air conditioner, H2 - 2-stage heat pump)  
for a few seconds, depending on DIP switch settings.  
The anticipator adjustment controls the sensitivity and cycle  
rate of the thermostat. Higher numbers decrease the sensi-  
tivity and slow the cycle rate. Lower numbers increase sen-  
sitivity and speed up the cycle rate. A limiting feature of the  
thermostat will not allow more than 4 equipment cycles per  
hour, regardless of the anticipator setting. Values can range  
from 1 to 9. The default is 3. The default selection will pro-  
vide optimum performance in nearly all installations. Do not  
change the setting unless there is a need to do so. Press the  
Mode button during configuration mode to change the set-  
ting. Use the Up and Down buttons to increase or decrease  
the value.  
IV. SET THERMOSTAT CONFIGURATION  
Configuration options, like DIP switch settings, are intended  
to be selected at installation and are not normally modified  
by the user. These options are not discussed in the owner ’s  
manual and must be done as part of the installation. A spe-  
cial procedure for the thermostat allows entry into the con-  
figuration mode. To enter configuration mode, press and hold  
the fan button for approximately 10 seconds. The room tem-  
perature display will disappear and dashes (--) will be dis-  
played on the thermostat screen. The thermostat will auto-  
matically exit configuration mode if no button is pressed for  
Unlike conventional thermostat anticipators, the setting is  
not determined by current draw. There is no need to mea-  
sure, know, or compensate for the current. There is no need  
to ‘‘droop’’ with this thermostat, regardless of the anticipator  
setting.
